Hi all,
I'm excited to announce the release of the Sipwise sip:provider Community Edition v2.6, a free and open source turn-key platform, which uses Kamailio, Sems and Asterisk in its core to provide a full-blown and feature-rich VoIP soft-switch.
http://www.sipwise.com/news/announcements/spce-v2_6-release/
New core features are *full presence/xcap/im support* together with the awesome Jitsi client, allowing you to deploy your own Skype-like service for encryted voice/video communication, buddy lists, instant messaging, screen sharing and remote desktop control. We also support *media features for error announcements*, like busy, blocked, unknown number etc.
Check our VM images to get started within a couple of minutes and learn what can be built with the power of Kamailio as a stateless load-balancer and a stateful proxy/registrar, and Sems as an SBC and application server.

Thanks a lot to all developers, contributors and members of this mailing list to make this possible and for helping us out!
